Patent EP-0390110-A3 (EP)
Title: Method of and apparatus for inspecting conductive pattern on printed board
IPC: G06T7/00
Filed: 1990-03-28
Abstract: A printed circuit board (11) is provided with a 
conductive pattern (P, R) and a through hole (H) thereon. 
Respective images of the conductive pattern and a through 
hole are photoelectrically read with an image reader (20). 
The conductive pattern image is magnified in size to obtain 
a magnified pattern image (PI m ), while the hole image is 
magnified at different magnification factors to obtain 
magnified hole images (HI n , HI n-i ). A ring image (RP) is 
defined by the difference of the magnified hole images. The 
overlapped region (WR) on which the ring image and the 
magnified pattern image overlap each other is then 
calculated, and a defect or an opening of the conductive 
pattern is detected by calculating the aperture angle (ϑ) of 
the overlapped image.

Title: Synchronizing signal separating circuit
IPC: H04N5/08
Filed: 1990-03-30
Abstract: A synchronizing signal separating circuit inverts and 
amplifies, in an inverter 12, a composite video signal 
received from a video amplifying circuit 100 through a 
coupling condenser 1. An output node B of the inverter 12 
is connected to an input node A of the inverter 12 through 
a switch 14 and a bias resistor 10. A bias resistor 11 is 
connected between the input node A and a ground potential. 
An output of the inverter 12 is further inverted and 
amplified by an inverter 13 and outputted as a composite 
synchronizing signal and also supplied to a control input 
of the switch 14. As a result, the switch 14 is turned on 
in a synchronizing signal period, so that the coupling 
condenser 1 is charged with the output of the inverter 12 
and also the electric charges of the coupling condenser 1 
are discharged through the bias resistor 11 in other 
period than the synchronizing signal period. Therefore, 
irrespective of a APL of an inputted composite video 
signal, it is possible to maintain a level difference 
between a top level of the synchronizing signal and a 
separation level to be constant to correctly perform 
separation of the synchronization.

Patent EP-0585043-A3 (EP)
IPC: G06T3/40
Filed: 1993-08-18
Abstract: An image enhancement method in which low-resolution bitmapped images may be 
enhanced and converted into gray images for printing on high-addressability printing and 
display systems. The method uses template (94) matching to determine a rendering goal, and 
converts the bitmap pixel into a numerical, multiple-bit-per-pixel sampled value (96) that is 
independent of the system it may ultimately be printed on. Unlike previous template matching 
methods which determined an enhanced pixel pattern output which was sent directly to the 
photoreceptor of a specific printer, the sampled data value of the present invention will 
require processing by the printer for its own particular characteristics before being sent to the 
photoreceptor. The sample data value may be sent directly to a printer imaging processor or 
stored via a network.

Title: Method and system for selecting data for migration in a hierarchic data storage system using frequency distribution tables
Inventor: BURKES THERESA A
IPC: G06F11/10
Filed: 1995-07-11
Abstract: A hierarchic disk array data storage system (10) has multiple storage disks (12) that define a physical storage space (34) and a RAID management system (16) that maps the physical storage space (34) into two virtual storage spaces. A RAID-level virtual storage space (40) presents the physical storage space as mirror and parity RAID areas where the mirror RAID areas store data according to RAID Level 1 and the parity RAID areas store data according to RAID Level 5. An application-level virtual storage space (50) presents the physical storage space as multiple virtual blocks which can be associated with mirror and parity RAID areas. The RAID management system (16) migrates the virtual blocks between the mirror and parity RAID areas to optimize performance and reliability. To select virtual blocks for migration from mirror to parity RAID areas, a frequency distribution table (60) is created to characterize the virtual blocks according to a predetermined distribution criteria. A virtual block is selected by segmenting the frequency distribution table (60) to identify virtual blocks. The application-level virtual storage space (50) is searched until a virtual block that satisfies the selection criterion is located. The located virtual block is then migrated to the parity RAID area. <IMAGE>

Inventor: EISDORFER ALLEN
IPC: H04Q3/00
Filed: 1995-11-21
Abstract: A telecommunications carrier other than the carrier of last contact is
arranged to a) recognize that the telephone to which a particular call is placed is a
disconnected telephone and b) provide different call treatment for the call, e.g.,
different call handling or different call features or services, as compared to the
treatment the telecommunications carrier provides for the same call to the same
telephone when it is recognized that the telephone is not disconnected.
Advantageously, no effort is wasted in an attempt to complete the telephone call to a
disconnected telephone. Such different treatments include 1) simply making no
attempt to route the call to the disconnected telephone via the network of last
contact, 2) routing the call to a secondary, alternate telephone, and 3) initiating
transmission of a page to a pager that is associated with the owner of the
disconnected telephone.
